SPECIFICATION forming part of Letters Patent No. 657,408, dated September 4, 1900.

' Application filed October 7, 1899. Serial No. 732,837. (No model.)

ToaZZ whom, it may concern:

.the following is a specification, and which are illustrated'in the accompanying drawings, forming a part thereof. i

This invention relates to that class of lubri-v cators usually employed for introducing a lu` `-bricant into a steam-cylinder or the like and to the top and bottom of which ,the steampressure is applied.

'lhe object of this invention is to adaptlu- Abricators of this class for the practical use of ciently to prevent it from becoming impacted.

The invention consists, further, in the various details of construction, as hereinafter fully described, and as illustrated in the accompanying drawings, in which- Figure 1 is a side elevation, partly in central section, of the improved lubricator. i Fig. 2 is a detail section on the line 2 2 of Fig. 1. Fig. 3 is a plan section on the line 3 3 of Fig. 2, and Fig. 4is a detail elevation of the carrier used for `transferring the lubricant.

In carrying out my invention I use areser- Voir or cup, preferably in the form of a cylinder 10, within which is located a follower 11. Across and opening-to the bottom of the cylinder 10 there is located a barrel 13, Within which plays a plunger or carrier 14, the inner surface of the bottom of the cylinder being recessed or depressed below thenpper line of the barrel, as shown at 50, and through a portion of its area being depressed approximately to the bottom of the barrel, as shown at V51, vfor the purpose hereinafter, more particularly pointed out. The carrier 14 is provided with a stem 15, projecting Athrough a stuiing-box 16 at one end of the barrel 13 and being connected by means of a pitman 17 and acrank-pin 17a with aratchet-wheel18,driven by means of Va spring-pawl 19, carried by a Y a delivery-duct 22, leading downwardly from the barrel 13 through the nipple 22, and which is connected with a steam-pipe 23 by means of a coupling 24, in the form of a "sight-glass tube, and which incloses the usual tube-section of glass 25. At the intersection of the nipple 22 with the coupling 24 there is placed a nozzle .26, which causes the lubricant-to enter and pass through the glass tubular section 25 in small masses, thereby affording a sight-feed. A steam-pipe 27 leads from above to the upper end of the f cylinder 10, and a branch thereof (shown as a duct 28) leads to the barrel 13 and opens thereto in alinement with the duct 22, so that when the groove or pocket 21 is in register with the latter duct it is also in register with the `duct 28, and hence the pressure in this duct causes the discharge of the lubricant from the groove. When the groove 21 is in communication with the chamber of the cylinder 10, it is filled with the lubricant by reason of the downward pressure of the follower 11 due to the steam -pressure and to its Weight and that of the water of condensation above it, so that each time the plunger or carrier 14'advances it carries a pocketful of the lubricant to the duct 22, into which it is discharged in the manner hereinbefore described. The carrier 14 is provided with a longitudinal duct 29, whereby a balance of pressure is insured at its opposite ends, so that itis free to reciprocate. A guide-stem 30 leads upwardly from the follower 11 into `a glass tube 31, provided for its accommoda- IOO form opens through the bottom ofthe cylin- Vbottom ofthe barrel 13, as shown atll, thef position in Fig. -thereby loosening orfagi-l d uct being identical with those leading from the duct `22, they need not be described. Steam-pressure may be applied to the barrel Y 13, so as to discharge the lubricant from the pocket 34 into the duct 35 in any desired man. ner. For this purpose I show apipe36, leading to a duct 37 cored inthe 'wall of thecylf inder lO, this. steam-passage being provided with a suitable valve 38, as is also the `pas-' sage 28, as shown at 42. y

The recess at the bottom of the cylinderl'O' constitutes its ednction-port,and extend-ing! below the top of the carrier 14 thegpockets 21 34 are open widely to the chamber of thecyl-'- inder 10, and this bottom being through al portion of its area depressed nearly to thel lubricant is free to enter the pocket from; above and both sides of the carrier'. Y l g A scraper or agitator 52 is `xed upon the carrier l4, so that it maytravel froml end :tot end of thefope'n portion of the barrel -l3--that is to say, from the solid lineto the dottedline tating the contents of the cylinder as the car-l5 rier is reciprocated and preventing thelubri-fi cant from becoming impacted and fromarch-l ing around the upper face of the carrier, so as to allow the 'pocket to Vslide `through the arch without being filled. While Ihave shown this scraper as being in the form of an-arm xedtransversely across the carrier, it-may be of any other desired shape, or, if preferred, may be actuated by other means than those disclosed. v g

A vent and draining cock 53.01? ordinary;

der 10 for the purpose of facilitating the withdrawal of the follower 1l and to provide zfor ;f draining off the water vof condensation prejf liminary to recharging the cylinder `withlu-fv bricant. p f

While I have shown pockets in` thecarrieri 14 as annular, they may be given any desired form, provided only that they are `adapted lto; receive the lubricant from the cylinder or cup l() and to register-simultaneously withafpressure-duct and with one of the receiving and conveying ducts 22 35.

The lubricator may be supportedin any de-l? sired manner. I show it as beingv providedl with a threaded stem 46, which forms a convenient means for attaching it to a rigid support. l I am aware that it has been proposedto provide lubricators with oscillating or recipro` cating carriersfor transferring the lubricant in measured quantities from a reservoir-or cup to a conveying-tube; but I believe my'-l self to be thefirst to provide in a lubricator of this type meanesffor applying fluid-pressure directly to the contents of `the pocket ofthe conveyer for the purpose of ejectingfthe same therefrom into the conveying-tube. The advantage of this in the use of graphite as alubricant is that the fluid applied under presalong the-tubs.

sure breaks up or disintegrates the material,

thereby not only looseningit from'the receptacleof the carrier' intowhichit is necessarily solidly compressed, but facilitating its passage along the duct of the conveying-tube, the fluid which has loosened it from the oonveyer serving also as a .vehicle for carrying it While I have hereinbefore referred to the 'xln-bricator as being in use in connection with steam-pressure, I do not desire to be limited Vto such application of the invention, as any tovthegupper face of theffollower l1 and within the duct 28. 'The conveyer 14 is caused to reciprocate by means of ythe lever 20. The

agitating-arm 5lv stirs up the graphite sufiivciently so thatvun'der the pressure applied to the follower ll itwill ll the pocket in the carrier, and whenthe latter is brought into 'register with the duct28.andnipple22ithe pressurewithin the former will dislodge the graphite 'from the pocket, causing it to fall into the nipple and to beconveyedtherefrom through the pipe 23-,to its `ultimate destinaftion, the water of condensation Within the duct 28 serving as a vehicle for conveying it through the lattertube.

When the lubricator is intended for use in 'connection with two cylinders or other parts to be lubricated, the valve rin the service-pipe .36is opened, andthe action upon that side of the lubricatoris the same as upon the opposite side. l

"Should it be desired to deliver the lubricant through the nipple 35 only, the valve in f1 the duct 28 is closed by means of the valvestem 42, so :that no pressure will be applied to the pocket 21, and hence it willnot be dischargedio'f its contents.
